My mail server uses a pretty standard setup to filter spam, that is Spamassassin. I get really good results, and use a SIEVE rule to move all the spams to a “Junk” folder.

The funny part is that some mails started to end up in the “Junk” folder over the last two weeks, although Spamassassin hadn’t marked them as spam… It turned out that the X-Spam-Status header included the word “BAYES_00″, and my SIEVE rule was “if X-Spam-Status contains yes, move to Junk”.
